Outstanding. Theo Walcott and Jamie Collins meet. Collins gives Walcott a pennant. Walcott has nothing to give in return. Embarrassing.

My word, how many mascots have Sutton got? They've emptied a primary school.

Sutton should never have beaten AFC Wimbledon. They should never have beaten Leeds United, so what's to say they can't beat Arsenal?
They've got the home pitch, the crowd and the community behind them, so anything is possible
Players huddling, slightly late kick-off. Arsene Wenger has appeared...
On the subject of the 4G pitch, surely Arsenal would prefer to play on the true artificial surface, rather than a rutted cabbage patch at the end wrong end of winter?
Anyway...

The neutral would love anything other than Arsenal winning but I can't see anything other than Arsenal winning this.
This is brilliant. Sutton boss Paul Doswell is on the pitch, beaming from ear to ear, conducting the crowd. He's gone to all four corners. Here come the players. You can hear the noise in Seattle.
The players are in the tunnel. Arsenal are all in tracksuit tops. Sutton are not. It's cosy in there...

Comedian and Sutton fan Tim Vine: "This is a small club and it's charming. If you look round it's like a 1970s throwback. I don't want too much money poured in as it might change it.
"If they were to beat Arsenal this would be the biggest ever FA Cup shock.
"Until the final whistle is blown I'm just going to dream the whole time."

A lusty blast of "Nessun Dorma" has just reverberated around Gander Green Lane to add to the atmosphere - almost ready for action between National League Sutton United and Premier League Arsenal in this FA Cup Fifth Round tie.
And "Sweet Caroline" to follow....

I can't stand playing on artificial pitches. They are a lot better than they were but when you are used to playing on grass with normal studs, it changes everything. It's certainly something Arsenal will have to overcome mentally.
If Sutton can get through the first 20 minutes without conceding, they can concentrate on the next 20 and try to get through the games in blocks.
Sutton definitely make the most of home advantage. Shots inside their dressing room show that its painted a bright white, rather than the dark brown of the away room. Almost time for the players to emerge...
Just over 10 minutes to kick-off. Lucas Perez and Alex Iwobi are currently arguing over the last peg in the away dressing room. Rob Holding hasn't got a seat. He's having to change on the floor in the middle of the room.

Sutton chairman Bruce Elliott: "I'm very relaxed, just taking it all in after three weeks of hard work. It's an unbelievable evening for this football club. Frighteningly, it's over 50 years since I started to come and watch, and this is my 20th year as chairman, which is slightly worrying because I must be getting old, but this is what the FA Cup is all about. Seeing Arsenal here is just surreal.
"It's life-changing. We've had a lot of things we'd like to do but never had the finance, so maybe now we can get them done. Every penny we've made will go back into the club to make it a more welcoming place and to make sure we continue progressing."
I kid you not. Sutton reserve keeper Wayne Shaw is adjusting the goalposts. He plays, coaches, helps on the ground and hoovers up. He'll be repainting the lines at half-time.

I was amazed with the reaction after the game last week. What's changed? That happens to Arsenal this time each year. They can still win the cup and can still finish fourth which has been more than good enough in recent years.

Wenger wants to play every game as it comes. He's a fighter. You saw that in his press conference after the Bayern defeat, almost throwing punches at anyone who doubted him.
It's an interesting dilemma if he leaves Arsenal. I think he will 100% be at the club next season. They don't want to see him go to Barcelona which is a possibility.

There should be enough in this team. If they have the right attitude and go about it from the start they should be beating a team like this. Arsenal have to go out with real intent.
To be honest, Rob, I'm not sure you should be thinking that "anything can happen". "Anything" would be bad news for Arsenal. You'd much prefer nothing to happen.
